Give a use to this
It seems pretty useless, 2x2x3 Here is the order, TOP: Redstone Block MID: Slime LAST: Sticky Piston https://preview.redd.it/7vzhrwv281x91.png?width=1920&format=png&auto=webp&v=enabled&s=ebff351e09b30e2a6cc0ca9f0dd83e80964ac2da
update to my previous post here: i tried the ideas in the comments (replace block under redstone torch with target, and place repeater before the block respectively) and it works, however it seems to instantly retract in, any idea how to fix this? (for reference, i am making an exit to a bunker)

Why does this dispenser not activate?
The right one doesn't activate, all the others do. (when the torch turns on) https://preview.redd.it/lve2g4uf6eo91.png?width=932&format=png&auto=webp&v=enabled&s=9c43b438faa6371c97ab7caf8d30182688a6769b

Budded Piston Problem
Im trying to make a device that makes the piston extend to make the player transfom into crawl mode but this piston keeps being power. [Circuit](https://preview.redd.it/2d65p6zsxm591.png?width=1297&format=png&auto=webp&v=enabled&s=1d7198c0ac8425767e0cac41ab674481cc673448)
(New?) Piston bug
So I discovered this bug where a sticky piston won't spit out its block when a 1 tick pulse is passed on the block over it. It causes the piston NOT to spit out its block on even -y axis values and on all +y axis values. the sticky piston DOES spit out the block on odd -y axis values. Here is a video of it, I have opened the F3 screen during the vid so that you can see what the position of the piston is in the "Targeted block:" part of the F3 menu. I am playing in Minecraft version 1.18.2. No mods. ​ https://reddit.com/link/ti1wzx/video/0cvb4gbxwdo81/player

How this piston extends, why the note block
Hi!, hope anyone can explain how does this system works. and what function the note block has. Im really new at redstone. Hope you have a cool day. https://preview.redd.it/gm1e7t7n9en81.png?width=1920&format=png&auto=webp&v=enabled&s=25738683041b03a7f61cd059fbe011118f0d56b6
Please help to understand why does this contraption work the way it does
The contraption is: a note block (random thing to create updates), 2 observers in a row, a sticky piston and a random block The question is: why doesn't it work as expected ( when rotated facing down? https://reddit.com/link/syv63j/video/m9y0izzdkfj81/player

The dropper is being powered whilst minecart with hopper is on detector rail, unloading blocks. The detector rail is on a transparent block and somehow still powering the dropper. Any way to fix this without removing everything and pushing the dropper one block further down?
How is this wireless stick piston even working?
Am I missing something? Did I overlook something? Is it because of a (not so) laggy server? Or is there - in the Minecraft redstone rulebook - that I miss a law? I'm new to redstone and am trying to figure out how does piston popout doors work and this happened. https://reddit.com/link/qy76sl/video/n7fgh3c9lr081/player
What is Quasi-Connectivity?

Some components (pistons and droppers for example) can be activated in a special way. If there is a source of power either diagonally or two blocks above them, they would be considered “quasi-powered”.
The effectiveness of this powering only takes place once the component gets updated.
What are BUDs?

For example, placing a block (usually) only causes block updates to the six blocks around. This means you can turn a piston into a BUD by placing a redstone block two blocks above it. It will not update the piston, but the redstone block will QC-power the piston. When the piston gets a block update from elsewhere, it will start extending.
BUD examples

The piston was powered when unable to push keeping it in an unstable state.
Bottom image: BUD with QC
The piston is BUDded diagonal. Note: the block on the left is necessary here.
QC applications

This is a 2x2 flush door that uses 12 sticky pistons to open a passage through a wall.
It first appeard here in August 2011 during the 1.7 release of the Beta edition.
